  STACK is sold as a per-seat SaaS subscription for full-access (estimator) users,
  billed annually, with unlimited viewer seats and unlimited projects included.
  Published Takeoff & Estimate tiers are Premium (takeoff plus GPT-powered AI chat)
  and Pro (fully integrated takeoff and estimating, marketed as best value), with a
  separate lower-cost Build & Operate product and a "Build Your Own" custom bundle.
  API access is NOT a self-serve add-on with public pricing: it requires a STACK
  customer account on an API-Enabled Subscription (or an approved partner
  agreement), and STACK also markets an "API + BUILD" bundle whose price is quoted
  on request. A free 7-day trial exposes Pro-level features. Exact figures vary by
  region, seat count, and promotion, and volume discounts apply as seats are added.
notes: >-
  Prices below reflect publicly reported figures as of mid-2026 and are not
  reconciled against a live quote. Per-seat prices commonly reported: Premium
  ~$249/user/month and Pro ~$299/user/month when billed annually; independent
  reviews also cite annual entry points (e.g. Standard ~$2,599/yr, Build & Operate
  ~$599/yr). API access pricing is quote-only - contact STACK.
